WolframAlpha and Spezify are two relatively recent websites that are quite innovative and interesting.

WolframAlpha is a computational knowledge search engine which is still under development. It will graph equations for you, and even map out syllable charts for any word you type in! There's much more than that though, type in a date and it will spit out significant events from that day. Very helpful for statistical and mathematical school work. There's a lot of good chemistry documentation there as well.

Making the world's knowledge computableToday's Wolfram|Alpha is the first step in an ambitious, long-term project to make all
systematic knowledge immediately computable
by anyone. Enter your question or calculation,
and Wolfram|Alpha uses its built-in algorithms
and a growing collection of data to compute the
answer.

It's quite fascinating really. Try out some of their examples.

Spezify is a very creative take on the common-day search engine. Type in any word and it will put a bunch of flash generated images of sites where that word is referenced. It's surprisingly accurate as well. You can even watch video results directly from the site, like a clean pop-up!

Spezify is a search tool presenting results from a large number of websites in different visual ways.

We take web search further, away from endless lists of blue text links and towards a more intuitive experience.
We want you to get a good overview of a subject,
find useful information and be inspired with Spezify.

We mix all media types and make no difference
between blogs, videos, microblogs and images.
Everything communicates and helps building the bigger picture.

We collect websites and are aiming to use as many relevant, free and open API:s as possible to generate extensive and diverse search results.

It seems to be a work in progress as well, but it is amazing. Type in your profile name and you may get a few things. I seem to have made my small mark on the internet, according to the results.
